Windows 7: Change "opens with" from 64bit version of prog to 32bit, not working

Hi, I am hoping someone can tell me what is going wrong here...

I have two versions of Sonar X1 Producer installed - the 64bit version and the 32bit version.

Sonar projects use the extension .cwp and by default open with the 64bit version, located at program files/cakewalk/sonar x1 producer/sonarpdr.exe

However, since the 64bit version is unstable, I wish to use the 32bit version to open the .cwp files

When I try to change the default "opens with", by assigning the default to program files (x86)/cakewalk/sonar x1 producer/sonarpdr.exe it doesnt change.

Is this because both exe files are titled the same, just that one is in the 64bit programs folder and the other is in the 32bit, and Windows is thinking they are the same program, hence it wont change it from the 64bit to the 32bit version of the exe?

Many thanks for your help!

I managed to suss it out, and so if anyone else has this problem, here is what you can do...

Open Regedit, and search for the exe that is giving you trouble.

Keep searching the registry until you come to the path that is incorrect, then edit it to the correct path.

Done
