I'm installing Qgis (Standalone 1.8) on all the PCs of the town planning office where I work. All good for 4 computers, on the fifth installation does not work.
Computers have all XP with SP3.
In particular: the installation seems to proceed normally until the end, then unlike the other pc, ends without the window appears as Microsoft Visual C++ and bypasses all the post-install.
After installation, the desktop icons are missing Grass, MSYS and OSGeo4W. There are Qgis Qgis desktop and browser, but will not start.
The same problem occurs with the previous version.
I can not figure out what is missing on this computer, which is mine.
Is there anyone who has had the same problem and fixed it?
