Problems Installing PostgreSQL 9.2

Question

I\'ve been trying to install the 64bit version of PostgreSQL 9.2 for Windows on my machine (Windows 7 64bit) and get this error:

The environment variable COMPS

Answer 1

It's not COMPSPEC it's just COMSPEC. Please show the output of:

echo %COMSPEC%

Note that COMSPEC could be set to something different in the Administrator account you're running the installer as. I'm not sure how to find that out, but it might appear in the PostgreSQL installer log, so please upload that and link to it in your post. See Reporting an installation error for info on where to get the installer log.

See the PostgreSQL for Windows FAQ entry Check the COMSPEC environment variable.

Here's a report I made suggesting that the installer should test for this explicitly and here's my blog post on the topic.
