I have a DLL file prepared by C# and my system is Windows 7 64-bit. When i apply the RegAsm its not adding the registry to 64-bit path but only adding it to 32-bit path.
"C:\Windows\Microsoft.NET\Framework64\v4.0.30319\RegAsm.exe" /register /codebase "C:\o.dll"
then if i check my GUID in regedit.exe i see that i have it only in 32-bit registry path: HKEY_CLASSES_ROOT\CLSID\{... my guid is found here ....}
instead of HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{... not found my guid ...}
As a result i have other issues for this. Can anyone please suggest what is going on and why its not making 32-bit and 64-bit registry entries?"
You have it backwards. The Wow6432Node is where the 32-bit specific data goes. Use the 32-bit regasm (from the Framework directory, not the Framework64 directory) to have your component registered in the Wow6432Node.
also, you probably compiled your dll with AllCPU option try to compile with x64 and/or x86 option and register like you do
- for x64 -
"C:\Windows\Microsoft.NET\Framework64\v4.0.30319\RegAsm.exe" /register /codebase "C:\x64\o.dll" - for x86 -
"C:\Windows\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe" /register /codebase "C:\x86\o.dll"
P.S. its 5yo question, but may be help to other peoples
