A. This problem is caused by the file called Comcat.dll

Here's the Solution

1. Click Here to download and extract the ZIP file. It contains Comcat.dll and Regsvr32.exe files.
2. Search for Comcat.dll file on your system and you'll find it in Windows System directory (C:\Windows\System for Win98 or C:\Windows\System32 for Win NT, XP etc).
3. Make a backup of this file, or rename it. Make sure you don't delete this file.
4. Now put Comcat.dll and Regsvr32.exe files which you have downloaded now to the system folder (C:\Windows\System for Win98 or C:\Windows\System32 for Win NT, XP etc). Note that you may already have Regsvr32.exe, in that case also take a backup of this file.
5. Now go to command prompt (MS-DOS) and put following commands

CD C:\Windows\System (Path may vary depending upon which OS you use)

Regsvr32 comcat.dll

You'll receive a message 'DllRegisterServer in comcat.dll succeeded.'

If this doesn't solve your problem then revert back above process. This way the original file on you PC will be in the system folder. Now right click the file and go to its properties. Click on the version tab and mail me its version number ASAP.

A. The file is provided along with the game and it is in .Cab file. The problem occurred because of some previous application you tried to uninstall. Which didn't remove the 'st6unst.exe' file. Following is the solution -

1. Search your PC for 'st6unst.exe' file. You'll find it in 'C:\Windows\System\st6unst.exe' or 'C:\Winnt\System32\st6unst.exe' depending upon which OS you are running. Now delete this file.
2. Also search for 'Vb6stkit.dll'. You'll find this in the same location of 'st6unst.exe'. If this file size (Vb6stkit.dll) is 0 (zero) then delete this file. Remember, only delete it when its size is 0 (zero) otherwise don't.
3. Now try to setup my game.

This will solve the problem.
