Unable to install Plan G

[Rimax]

Hello everybody.
I downloaded Plan G v.3.0.2 (build 51) but I can't install it. I get an error screen from Windows and it stops automatically. First, I had uninstalled old V3 version according to "read me" instructions, but now I can't install either the new or old version.
Any idea about the problem ? Thanks

What does the error say?

Its the classical screen "Windows Installer has detected a problem and must close. Inform Microsoft about this problem .......... (Send Report) (Not Send)". 
Find enclosed a Screen capture of the error.

What OS? And what version(s) of DotNet do you have installed?

[Rimax]

My OS is Windows XP Sp3. As DotNet I can see .Net Framework 1; 1.1; 2 SP2; 3 SP2; 3.5 SP1 and 4 in the programs list.

Hi. Tim:
Finnaly I solved the install problem. I just downloaded Windows Installer V 4.5 from Microsoft downloads, and here we are. Plan-G working correctly.
The file for XP Sp3 is: KB942288 v3.
