Re: Re: TortoiseProc Launch failed

I have been getting the dreaded "TortoiseProc failed to launch" error. The
error occurs when I upgrade TortoiseSVN 1.7.3 to 1.7.4 or 1.7.5. When I go
back to 1.7.3 everything is fine again. I have tried the posted solution
described below but, unfortunately, it does not work for me.

I run TortoiseSVN under Windows 7.

Here are few additional facts that may be relevant:
1.) After I upgrade to 1.7.4/5, when I right-click on the local copy of an
archive, I cannot see the Commit or Update commands in the pop-up menu. The
number of items under the TortoiseSVN submenu is very small (Repo Browser,
Settings, Help, and About).
2.) If I click on any of the available TortoiseSVN commands, I get a dialog
"TortoiseProc Launch failed: The filename, directory name, or volume label
syntax is incorrect."
3.) If I right-click on the desktop (or another folder not linked to
Tortoise) I see more items in the TortoiseSVN pop-up menu (Repo-browser,
Export, Create repository here, Import, Settings, Help, and About)
4.) If I right-click on the desktop and select Repo-browser, TortoiseSVN
launches the Repo-browser and tries to direct it to a URL on the clipboard.
For example, if I first copy www.google.com, the Repo-browser suggest the
URL http://www.google.com/. When the clipboard does not contain a URL, the
Repo-browser suggests the most recent correct repository URL and
successfully opens the repository in the browser.
5.) If I navigate to ~\Program Files\TortoiseSVN\bin and launch any of the
*.exe files by double-clicking they launch without complaint.

I am hoping someone can suggest a cure for this before I fall too far
behind the current TortoiseSVN release.

Thank you,
