[cvsnt] Looking up *_protocol.dll

[Torsten Martinsen]

I have just discovered that recent CVSNT versions will always try to 
load the protocol DLL's from the path stored in the registry value 
HKEY_LOCAL_MACHINE\SOFTWARE\CVS\PServer\InstallPath.

This means that if you have two different CVSNT versions installed, they 
will both attempt to load the same protocol DLL's - this will obviously 
fail in one of the cases.

I am pretty sure this behaviour is new, and it causes problems for 
people who have installed CVSNT and then install a TortoiseCVS version 
including another CVSNT client. Can anyone explain
1) why the protocol DLL's are not always loaded using the path of 
cvs.exe (which the code does fall back to in case the registry value 
does not exist); and
2) if there are any unwanted side effects to deleting the registry value?
