The executable does generate its temp dir name at run time, but it is entirely
predictable before (and after :) When not using -C, it is $ENV{TEMP} plus
"\par-$USER"
(where $USER is the login name) plus "\cache-" plus the SHA1 hash of the
executable.
For example:
c:\temp\par-astewart\cache-1a6deca675169d47838e9faf5a23cfb644890bad
on my environment, where:
TEMP=c:\temp
USERNAME=astewart
and the SHA1 for the executable is 1a6deca675169d47838e9faf5a23cfb644890bad.
You can
compute the SHA1 as soon as you've run pp to put in an un-install routine.
On the other hand, if that's too much, you can set PAR_GLOBAL_TEMP to something
and the
PAR will unpack right there, without any par-$USER or cache- xxx stuff. Of
course, all
PAR executables will unpack there.
On the third hand, if you are not using "pp -d", the unpacked executable in the
temp
cache has the same name as the original PAR executable, you could search TEMP
for it
and delete whatever directory you found it in.
Note that if you edit the application and re-run pp, the application has a
different
SHA1 hash and uses a different temp dir.
