Hello All,

I have one 64 bit applicatoin , which uses some 32 bit graphic exes.
While i am doing createprocess for that 32 bit exes , its looks for registry path in "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MyApp" .
But as my application is 64 bit , all registry entries is in
"HKEY_LOCAL_MACHINE\SOFTWARE\MyApp".
As result creatprocess fot 32 bit graphic exe fails.
My Question is that "Is there any way so those 32 bit exe also looks for there registry path in default 64 bit registry path instead of wow6432node ?"

P.S. I cant convert those 32 bit exe into 64 bit as I don't have the source code for those 32bit graphic exes .

Please provide me any help to resolve this issue.

Regards..

There are several things you can do:
1. In your 64-bit application, copy all entries under HKEY_LOCAL_MACHINE\SOFTWARE\MyApp to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MyApp. AFAIK, explicit access to Wow6432Node in 64-bit programs is allowed.
3. If your 32-bit application can get these entries from an alternate source, provide that. For instance, I've seen applications that expect parameters in the command line; if those weren't provided, the application reads them from the registry; if not present, the application uses default values. If the 32-bit application you use can accept parameters in the command line, you can read the registry in the 64-bit application and pass them.

Hope this helps,
Pablo.

There is no way so those 32 bit exe also looks for their registry path in default 64 bit registry path instead of wow6432node ?"

The only possible solution is to port 32 bit exe into 64 bit :-)
