drive of windows installed

ghkumarmvk · 19th May 2009, 07:02

sir,
anybody have the code of getting the drive name (eg: C:\, D:\) where windows installed for a nsis file? . i created a setup program to install my program using nsis. now i coded C:\ or D:\ directly on the code, but i want the setup program to check whether the windows installed on C:\ or D:\ and that drive letter shown in setup program to install .
any help??
with regards
G.H.Kumar

you could just make use of e.g. $SYSDIR (the full path to the system32 folder, which I think you can't change from the windows installation drive's; unless you did some major hacking after install, I suppose), and then just grab the drive from that using string manipulation.

StrCpy $YourVar "$SYSDIR" 3

This will give you C:\

Change the number to change the number of characters (i.e. 1-C, 2-C:, 3-C:\, etc)
