Frequently Asked Questions (FAQ)

Installation

If I install a new version, will the installation remove the older one? Can both versions be installed on the computer?
The older version will not be removed. By default new versions will be installed in separate directories. Just make sure an older version is not running when a new version is being installed.
When I install RESRAD (onsite) with AVG installed on my computer I get an antivirus error.
The file CorrRegR.exe is used during RESRAD runs and assists in the calculations. However its name is similar to that of a virus, so AVG identifies it as malware. An exception may be made in AVG by following the steps in this FAQ after CorrRegR.exe has been extracted.

Running

When I start RESRAD I get a message stating "Run-time error '713': Class not registered…".
To correct this error, you will need to register a file. This can be done by issuing the DOS command "regsvr32 c:\windows\system32\dao360.dll". This may require administrator privileges for Windows Vista and Windows 7/8 operating systems.
When I start RESRAD I get a message stating "Run-time error '339': Component 'VCFI32.OCX' or one of its dependencies not correctly registered: a file is missing or invalid".

To correct this error, you will need to replace and register an active control following the procedure below. This may require administrator privileges.

  1. Backup the current vcfi32.ocx and vcfidl32.dll files in the system folder; the default path is C:\Windows\System32 for a 32-bit system and C:\Windows\SysWOW64 for a 64-bit system. For example, you can simply rename the two files to vcfi32.ocx.bk and vcfidl32.dll.bk, respectively.
  2. Download the vcfi32.ocx and vcfidl32.dll files from the RESRAD website.
  3. Copy the two files to the system folder; the default path is C:\Windows\System32\ for a 32-bit system and C:\Windows\SysWOW64\ for a 64‑bit system.
  4. Launch the Command Prompt as administrator by right-clicking and selecting "Run as administrator". Selecting "Run as administrator" may be required even if you are already logged in as an administrator.
  5. Register the vcfi32.ocx active control by typing commands as follows:
    • For a 32-bit operating system, type:
      regsvr32 /u c:\windows\system32\vcfi32.ocx, and then press Enter
      regsvr32 c:\windows\system32\vcfi32.ocx, and then press Enter
    • For a 64-bit operating system, type:
      regsvr32 /u c:\windows\SysWOW64\vcfi32.ocx, and then press Enter
      regsvr32 c:\windows\SysWOW64\vcfi32.ocx, and then press Enter
When I try to start RESRAD, the opening banner screen appears on my screen, and just stays there.

An error has occurred in RESRAD and the opening splash screen is blocking the error message. To minimize the splash screen so the error message will be visible, follow these steps:

  1. Right-click on the RESRAD icon on your desktop.
  2. Click Properties.
  3. Make sure the Shortcut tab is selected at the top.
  4. Near the bottom of the Properties box, there is a Run: box with a down arrow on the right side of it.
  5. Set the Run: box to Minimized.
  6. Click OK.

Now when you try to run RESRAD, the splash screen will be minimized and the error message will be visible.

I get an error message stating "Error '3170' run time. Couldn't find installable ISAM" after starting RESRAD.
The wrong version of MSVBVM60.dll is registered on the computer. Refer to Microsoft Knowledge Base article #Q299457. Or for users that run versions of Windows other than English, a missing vb.dll could be missing. Refer to KB article #Q273458. For instance, if the user has a French version of Windows, VB6fr.dll will be required.
Why do the tables show blank cells without data in RESRAD-BIOTA 1.8 results screen and Organism-Specific Parameters screen?

This problem is typically seen in Windows 7 or 10 with very recent updates of some Visual Basic 6 controls which are used by RESRAD-BIOTA 1.8, particularly DBGRID32.OCX and GRID32.OCX. A newer version of DBGRID32.OCX (newer than Version 5.1.81.4 released by Microsoft on 6/26/1998) or a newer version of GRID32.OCX (newer than Version 4.0.29.8, released by Microsoft on 1/11/2016) may cause the above-mentioned issue.

This issue can be corrected by replacing the active controls DBGRID32.OCX and GRID32.OCX with their earlier versions. This may require administrator privileges for operating system.

  1. Backup the current DBGRID32.OCX and GRID32.OCX in the system folder; the default path is C:\Windows\System32 for 32-bit system and C:\Windows\SysWOW64 for 64-bit system. For example, you can simply rename the two files to DBGRID32.OCX.bk and GRID32.OCX.bk, respectively.
  2. Obtain a copy of DBGRID32.OCX (Version 5.1.81.4) and GRID32.OCX (no newer than Version4.0.29.8) from online or an older computer. You can download these two controls from RESRAD website. Please note that if you download the ActiveX controls from Microsoft website, the ones you download are very likely newer versions that may not resolve this problem.
  3. Copy the two ActiveX controls to the system folder; the default path is C:\Windows\System32\ for 32-bit system and C:\Windows\SysWOW64\ for 64-bit system.
  4. Doing Step 1-3 should resolve the problem and the grid data in RESRAD-BIOTA 1.8 should display properly. However, if not, please register the two ActiveX controls following these steps:
    1. Launch the Command Prompt
      • For Windows 7 and earlier version of Windows, click Start > Accessories
      • For Windows 10, click Start > Windows System
    2. Right click Command Prompt and select "Run as administrator". The Command Prompt window should pop up.
    3. In the Command Prompt window
      • For a 32-bit system, type:
        regsvr32 C:\Windows\System32\DBGRID32.OCX, and then press ENTER
        regsvr32 C:\Windows\System32\GRID32.OCX, and then press ENTER
      • For a 64-bit system, type:
        regsvr32 C:\Windows\SysWOW64\DBGRID32.OCX, and then press ENTER
        regsvr32 C:\Windows\SysWOW64\GRID32.OCX, and then press ENTER

Now when you run RESRAD-BIOTA 1.8, the grid data should display properly. Please be aware that the above replacing the two ActiveX controls DBGRID32.OCX and GRID32.OCX with their earlier versions may cause some incompatibility with other Visual Basic programs. This potential issue does not affect your operating system and the potential incompatibility with other Visual Basic programs can be easily solved by restoring your backup of the two ActiveX control to your system folder. Again, the default system path is C:\Windows\System32 for a 32-bit system and C:\Windows\SysWOW64 for a 64-bit system.

International

I am using the RESRAD codes internationally, and I encountered an error or unexpected results.

International users may encounter a variety of problems relating to the use of a comma "," instead of a period "." for a decimal point, including the following issues:

For the RESRAD codes to run correctly, the number format must be set to "English (United States)" and the default keyboard should be set to USA. The number format may be updated as follows:

Legacy

After I installed RESRAD on a Windows VISTA machine, I receive an error message when I attempt to run RESRAD.

This problem stems from Vista's increased security measures. The workaround is to install RESRAD into a directory that is not under the Program Files folder (which is the default for the RESRAD installation). It is best to uninstall RESRAD first, and then run through the installation process for RESRAD again. When the installation asks you which directory you would like to install to, be sure to choose a different directory (i.e. C:\RESRAD_Family\RESRAD).

When I start the RESRAD installation, I receive an error indicating that there is not enough space on the hard drive and the installation stops.
The installation program needs to place temporary files in it to run properly. To safely clean out your TEMP directory, click on My Computer, then right-click on the C: drive. Select 'Properties' and click on the 'Disk Cleanup' button. Make sure the Temporary Files check box is selected. If you want to keep the files in your Recycle Bin or Temporary Internet Files, simply uncheck the boxes next to the corresponding item. Once your TEMP directory has been emptied, you should have no problem getting the RESRAD installation started.
Whenever I attempt to run a RESRAD case, I receive an error saying "Printer Error" and the execution stops.

In order for RESRAD to run properly, the computer it is installed on must have a printer installed. An actual printer does not have to be connected to the computer, but the software must be installed. To install a printer on your computer, follow these steps:

  1. Go to the Control Panel
  2. Click on Printers
  3. Click Add Printer
  4. Install any printer (It does not matter which one)

This error has been resolved in version 6.2 and higher.

Some codes (RESRAD-{ECORISK, BASELINE, CHEM} don't run properly after installing. What can I do?
These codes are no longer updated. RESRAD-CHEM and RESRAD-ECORISK run under Windows95's DOS but show various issues when running under new operating systems. RESRAD-BASELINE is a Windows95 code.
Does the uncertainty analysis only work with the transfer factors? For example, if the dimensions of my contamination zone or the unsaturated zone parameters have uncertainty, how do I account for this?
The uncertainty analysis for all other parameters can be accessed by selecting the parameter entry box and pressing the "F8" key.
