Frequently Asked Questions (FAQ)

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

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.

Delete the RESRAD.INI configuration settings file from the installation folder (default location is C:\RESRAD_Family\ONSITE\7.2), then try starting RESRAD-ONSITE again.

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 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:

• When attempting to run RESRAD codes, the results window displays "Fortran abort.....view the Output.fil file". The Output.fil file contains a line stating "Invalid decimal character , was detected (unit=internal)".
• Changing measurement units produces unexpected results.
• When attempting to run calculations in RESRAD-BIOTA, error 3464 displays, and then RESRAD-BIOTA closes.

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:

• Windows 10 and Windows 11
  • Type Control Panel in the Search box to open the Control Panel.
  • Under the Clock and Region category, click Change date, time, or number formats.
  • On the Formats tab, change the Format to English (United States).
• Windows 7
  • Go to the Control Panel and select the Clock, Language, and Region category.
  • Under Region and Language, click Change the date, time, or number format.
  • On the Formats tab, change the Format to English (United States).

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).

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.
