ibm system i access error 1327

Where I work we (like most companies, I would imagine) have our My Documents folder automatically mapped to a drive on a network. I'm not sure if it's expressly this, or the fact that the drive is on Network Attached Storage, but either way we get:
Error 1327.Invalid Drive: :\
from the IBM System i Access for Windows Installer InstallShield Wizard when it's trying to computer space requirements.
Here's the fix:

1. Save any open documents!
2. Open regedit
3. (insert warning about the risks of modifying your registry here!)
4. Browse to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Personal
5. You should find the offending drive letter here
6. Change it to a local drive (double click "Personal" and type in "C:\" without the quotes, for example, but if you don't know how to do that, call your IT professional)
   
7. Install iSeries Access
8. Repeat steps 4-6 above, but change it back to the offending drive
9. Enjoy convenient access to your iSeries!

Hope that helps someone out!
