So...
I have this game called Europa Universalis III. I had recently bought the complete edition after this, as it included the expansion packs and was cheaper than the individual downloads of expansions. I had been able to play the normal Europa Universalis III well, but the graphics would not load correctly, and so I would always have messed up colours. When I uninstalled Europa Universalis III, and tried to install the Complete edition, it always loads InstallShield Wizard, and then says, "An installation support file could not be installed. Access denied." And when I try to reinstall my original edition, the same thing happens.
I haven't been able to play my game in about 6 months. Can anybody help? Oh and my Specs are:
Pentium 4 CPU, 2.80 GHz
2.24 GB RAM
128 MB video card(intel) model 82915G/GV/910GL Express
