Invalid Drive Y:\

I was trying to install Opera 9.5 today and during the installation I got an error. Error 1327.Invalid Drive: Y:\ I'm not sure why its even accessing the drive because its just a mapped letter drive to my local development server. I also got the same error when installing a trial version of Adobe Dreamweaver CS3. I've installed other software including Photoshop CS3 while I had the drive letter mapped.

I'm running Vista x64 Business SP1.

Anyone else ever run into this problem? I removed the drive letter and tried again, still same error. After that I restarted while the drive letters were removed and got the error again. Seems like all my installations are trying to default to the Y drive letter. Would this be something I can easly check/change?

I looked at the command line options for msiexec.exe which is the Windows Installer executable. To my surprise, there is no switch that allows to user to specify the system drive.

I don't know if you would get the same error message if you tried to update the installer but you could try it.

To check what version you have, open a command prompt and run:
msiexec.exe /?

I believe 3.1 is the latest.

Windows Installer. V 4.00.6001.0

This will most likely help. Follow the instructions in part B of the fix very carefully and be sure to repeat the steps with the additional keys listed.

Well in a way that fixed the problem. None of the drive letters were "wrong" but It did make me thing of something while looking at them. I store all my pictures on my file server and I have my Pictures, along with my Music folder, pointed to one of those drives mapped drives. I set the folders to the defaults and everything installed perfectly.

Thanks

I see. That would definitely do it. Glad it got your brain working. Cheers.
