NSIS 2.46 IsDotNETInstalled not working in XP SP3
I am a newbie to NSIS and couldn't find a solution for the following problem other than downloading and using DotNetVer.nsh.
I used the IsDotNETInstalled script in an installer which works fine on Win7. However, in XP SP3 the script insists that DotNET is not installed on the machine although I have installed the required version of DotNET
Is the system call not working in XP SP3 or do I miss something else?
The script I am refering to is from appendix C.2 in the help file.
