1) Install the software onto the PC that has Windows 7, 8, or 10, making sure that you perform the installation using an Administrator level User.

2) Go to the folder location holding the program file (C:\Program Files (x86)\NIC\”YOUR SYSTEM”, i.e. RA3Win, MA3Win, etc.). Right click on the program file (i.e. RA3Win.exe or MA3Win.exe) and go to Properties. Click on the Compatibility tab at the top of the window, and then click “Change Settings for All Users”.

3) Click to set the program to "Run in Windows XP, Service Pack (2 or 3)". Now towards the bottom of that window, check the box for "Run as Administrator", then click OK to each window until they're all closed.

4) Try to open the software and note the file name that is displayed in the error message, typically ending in .ocx. If the error message is hidden by the splash screen, use the mouse to click the header of the error message (should be an edge or corner showing) and slide it out to the side where it is now visible.

5) Under the C:\Windows\System32 folder, paste the corresponding file (i.e. MSCOMM32.ocx). If the file is already present, there is no need to replace the current file. If you do not have the needed file, the file can be downloaded offline, or you may contact AGS Scientific for a link to download the file.

6) Click on the Windows Icon in the lower left of your display (Windows Logo or Start) and type "CMD" (don't include quotes) in the Run or Search box there. For Windows 10, type into the search box to the right of the Windows Logo.

7) When the CMD program (“Command Prompt”) shows up in the display, right click on it, and select "Run as Administrator". A command prompt will open in a separate window.

8) Once you have the command prompt open, type the following command, regsvr32.exe /u followed by the complete filename from the error message and hit "Enter":   Here is an example:

                                                                                                     

                                         

9) If successful, you will be prompted with a notification that the unregistration of that file was successful.

10) Try to open the software again. If another error occurs, repeat steps 4 through 8 until the software properly opens. This should take no more than 3 or 4 tries maximum.
