installshield "Object reference not set" problem

Hi everybody,
I recently tried to install a game. 2 minuntes the installshield wizard starts, it shuts down with the error "Object reference is not set".
I did some research and found this:

i followed the instructions given (for version 11), and when i tried to install the downloaded file, the installation just crushed (Setup.exe has stopped working, so annoying :()

im using windows 7 32bit. every installation i tried worked so far. the game is not corrupt, because ive installed it before several times. i also tried to re download the game - same problem.

thanks in advance,
Ben :)

Which game are you trying to install? What is your computer specifications? Try to do the following suggestions given to fix the issue:

Click Start and then click Run.
In the Run dialog box, type the following command, and then click OK:

C:\WINDOWS\Microsoft.NET\Framework\v1.0.3705\gacutil /i C:\Program Files\Microsoft.NET\Primary Interop Assemblies\adodb.dll

There is another work around to this problem, you must avoid using XML attribute characters that are not valid. Do not use the "#" character and the "&" character in the project path.
