Summary: Uninstall Python shortcut does not work

Initial Comment:
I get a box 'This action is only valid for products
which are currently installed'.
Uninstalling with Control Panel -> Add/Remove works fine.

Thomas, do yourself a favor and Google on "Raymond Chen 
add remove" -- you'll find an hilarious/depressing weblog 
about *why*add/remove is so slow to come up in modern 
Windows.  Believe it or not, there are impossible-to-fix 
reasons for it!

There was a bug in the script that would use different
product codes for an alpha (i.e. the "final" product code)
for uninstall. I have fixed this in my CVS sandbox before
the release of 2.4a0, but not yet committed - will do so
tomorrow.

Hm, it works for Martin's MSI (the one downloaded from
python.org), but not for those created myself from the CVS tree.

Using the menu entry is much faster for people testing the
installers (Add/Remove take a long time to open on my
machine).  Normal users shouldn't uninstall Python anyway ;-)

[5 minutes later]

I guess he has set 'alpha = 0' in the msi.py script he used
to build the installer.  The 'alpha' version seems to use
two conflicting product codes for the MSI: one hardcoded, at
the top of the script, the other created by
msilib.gen_uuid() at line 81.

I'll try it out again, and report back.

Curious!  The Uninstall Start Menu entry for 2.4a1 worked fine 
for me, WinXP Pro.

If it's a "deep" problem, I expect we could just toss the 
Uninstall menu entry -- all versions of Windows I care about 
<wink> have the Add/Remove gimmick, which most Windows 
users expect to use for uninstallation anyway.
