Hello,
I'm running on vista and I'm getting a permissions error from win32com.
I attached a print screen displaying the error message. It appears
win32com is trying to write a file and vista UAC is blocking it. Why is
win32com trying to do this and how do I fix it? the only method I am
using from win32com is "win32com.client.DispatchWithEvents()" to create
a client of a windows OPC server. It works fine until I compile it and
run it from the compiled executable and this message appears.
thanks,
Jeff
There are 2 general solutions to this:
* Follow the instructions at
http://www.py2exe.org/index.cgi/IncludingTypelibs to allow py2exe to
include the pre-generated version of the makepy files you need at
runtime. This saves work on each installed PC, and also avoids needing
to have the typelibs included on each target PC (the usually will be
available, but depending on a number of things, may not be)
* Tell py2exe to avoid including anything in the win32com\gen_py folder.
If no such folder exists as win32com initializes, it will use a folder
under %TEMP% for this purpose - but if it does exist - even inside a
read-only .zip file or in a read-only directory - it blindly tries to
use it. As you are seeing, this will fail for stuff installed under
"Program Files" - you need elevated permissions to write there.
The first is the best general option - you don't have to rely on writing
anything anywhere to achieve something which works (but it isn't clear
you are using py2exe - so while that specific advice may not be
applicable, the general idea is (ie, ship with a pre-populated
win32com\gen_py folder)
