RE: [Visualpython-users] Problem installing on WinXP SP2

[SNOSWELL, M. <mic...@ba...>]

Thanks for the many responses!

I uninstalled all previous Python versions and reinstalled just 2.4. No
mention was made of problems writing to the Windows Registry during the
install process by Python24.=20

I definitely have write access to some parts of drive C: This PC is =
part of
the company's network (this part has about 2500 users) so they lock =
things
down pretty tight to minimise support issues.

Vpython install fails in exactly the same way as before.=20

I installed it last night on a PC at home for which I have =
administartor
access and there and no problems.

The problem appears to be twofold:

1. The Vpython installer fails to find the current C:\Python24 =
directory and
gives an error saying it can't be found. It is there. What test in the
installer doing to try to find Python? Why isn't it just looking for
C:\Python24 rather than (as appears to be the case) looking into a =
Registry
entry that it seems not to be able to find (but for which the Python
installer did not complain when it supposedly couldn't create it).

2. When the Vpython installer goes on to ask which directory to install =
to
it seems to ignore the directory I specify (C:\Python24), tests for =
Python's
presence again (and again says it can't be found) then finally gives an
error that a directory has not been specified.

I've installed Python and lots of extensions many times under IRIX and
Linux. Is there anything special about the windows install? Can VPython =
be
distributed as a ZIP files instead that I can unzip into
C:\Python24\lib\VPython??

Thanks for you help thus far guys
