Your problem could be more than just an installation issue. For instance you might want to make sure you are differentiating 32bit vs. 64bit registry entries: For instance in some situation I get my installed directory from the registry: RegisteredInstalledDirectory = ""; if (SYSINFO.bIsWow64) then folder = "SOFTWARE\\Wow6432Node\\myCompany\\myProduct"; else folder = "SOFTWARE\\myCompany\\myProduct"; endif; key = "InstallLocation"; type = REGDB_STRING; size = -1; RegDBSetDefaultRoot (HKEY_LOCAL_MACHINE); if (RegDBGetKeyValueEx (folder, key, type, value, size) < 0) then WriteLog("RegDBGetKeyValueEx failed for InstallLocation."); else StringTrimRight(RegisteredInstalledDirectory , value); endif; There are some other things you have to consider. Can you possibly run your setup.exe and generate a log? ... View more

The harder way would be to perform the GAC programmatically in using C# and writing your own uninstall and install for GAC and NGen. In C# there is a way to GAC your assembly: using System.EnterpriseServices.Internal; public class Helper { public Helper (){} //-- do this after all files have installed with NOT REMOVE = "ALL" condition public void GACInstallAssembly(string installDirectory, string assemblyName) { Publish publish = new Publish(); publish.GacInstall(installDirectory + assemblyName); } //-- do this after ValidateInstall with REMOVE = "ALL" condition public void GACRemoveAssembly(string installDirectory, string assemblyName) { Publish publish = new Publish(); publish.RemoveGAC(installDirectory + assemblyName); } } For NGening using NGen 2.0 use Process to run the command line: /C C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\ngen.exe install "C:\assemblyName.dll" /ExeConfig:"C:\myExePath.exe" look at: http://msdn.microsoft.com/en-us/library/6t9t5wcf(VS.80).aspx Have fun 😄 Yama ...

make sure you have .NET framework 1.1 installed on your client machine... IS2009 is behind in technology of GAC and NGen... They use .NET 1.1 ususally located in %windir% C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322 It contains gacutil.exe and ngen.exe... The NGen.exe in version 1.1 allowed multiple assembly to get GAC; however, in 2.0 and greater .NET you are only allowed to to GAC a single assembly at a time. In order for your GAC and NGen to work make sure your client installs .NET 1.1. In your installer go to the Search folder and look for ngen and let it search for version 1.1 not 2.0. Let me know how far you get with this. Yama ... View more
