[Visualpython-users] Problem installing on WinXP SP2

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

I downloaded Python-2.4.1.msi and it installed fine into c:\python24
 
I downloaded VPython-Win-Py2.4-3.2.0.exe and when it installed I get a
dialog box saying "Could not locate where Python 2.4 is installed. You will
be asked where to install the Vpython extension."

I click ok and then I get a directory chooser. From here I type in or Browse
to c:\python24, or c:\vpython, or c:\python24\libs or
c:\python24\libs\vpython. Nomatter which of these I try, or if I make the
directory manually, I always get an error box saying "Could not locate where
Python 2.4 is installed. You will be aske where to install the Vpython
extension."

I click ok on this and I get the "Select Components" box. I leave everything
selected. I click Next. I leave "Create a desktop icon" selected. I click
next. I get the Ready to Install box with the summary of what'll be install.
The destination directory looks ok (whatever I specified it to be earlier).

I click the Install button and I get an error box "You must enter a folder
name." I click ok and the installation terminates.

I've tried setting PYTHONPATH env variable. I tried rebooting (to pick up if
python2.4 neede this). I had Python 2.2 previously installed and running
fine and 2.4 runs fine.

I am do NOT have administrator access on this machine but did not need it to
install and run python.

What am I doing wrong?

Thank 

Michael Snoswell

I once had a similar problem.  The problem was that I did not uninstall
the old python before installing the new one.  This would only be an issue
when python bumps to a "new directory".  I'm guessing there's a registry
issue somewhere.

I'm a little concerned about the privilige issue.  I'm no expert here.  I
suppose you shouldn't have been able to do the installation.  The fact
that you were able to seems to indicate that you have write priviliges to
c:\ . That would be odd.  Perhaps (???) you somehow have write priviliges
to c:\, but can't write to the registry ???

If you haven't wiped out 2.3, the best thing may be to go back to 2.3.  I
haven't upgraded yet.  (I'm waiting for a scipy installer for 2.4)

Next best: (IMHO) Try uninstalling all your pythons and then reinstalling
2.4.   You have some privilges, you may have enough to clean out the old
and bring in the new.

It shouldn't matter that you have other versions of Python present; I 
have Python 2.3 on my machine as well as Python 2.4 and haven't seen 
such a problem.

Can you say more about not having administrator access? As Gary Pajer 
comments, it seems odd that you could install Python if you're 
explicitly locked out of being permitted to do software installations. 
There is an option (or at least there use to be) to install Python in 
your own documents if you don't have installation permission. In such a 
"registry-less" installation the registry is not touched.

My best guess is that somehow you managed to install Python 2.4 without 
the registry being updated, so that the VPython installer's first 
attempt to find python2.4 fails. It is possible that the VPython 
installer then does the wrong thing after asking you for a location, and 
I'll look into that later today. Thanks for the report.

I have similar problems with installing Python and VPython on my lab 
computers running Win2000. Our IT guys don't give faculty admin 
privileges on our lab machines. I can't install either Python or 
VPython correctly and IDLE will not run without admin privileges. 
They've set up a hack using something called "tcqrunas" to make it run 
but it still doesn't work correctly. Specifically, IDLE doesn't know 
where any VPython programs are and the default save directory was at 
one time visible to the entire network. In one class students were 
unknowingly overwriting each other's programs by saving their own 
programs with the same name. Changes were showing up without 
explanation! Our IT guys either can't or won't fix it. So much for 
competence.

Michael,

I've seen this before.  I assume you're installing to a Windows PC.  It alw=
ays happens when I forget to log on to my Windows machine as administrator.=
  Uninstall Python, log in as the administrator (for that machine), and try=
 it again.

Hope this helps.

Joe,
  How tightly locked-down is your computer lab? In particular,  I'm wondering 
whether a live-cd solution could work for you.   Now that vpython is in 
Debian, building a custom live-cd should be relatively straightforward, 
starting from Knoppix or morphix or ubuntu. 
  If anyone's already built one, please speak up!  (I don't recall mention of 
one on this list.)

I once rigged up an Autorun.ini that would load Idle when a host CDROM
disk was inserted to a standard Windows machine.  Here is the message I
posted to the list about it last year:
