I can't seem to compare two strings. One is read from the registry the other is the actual product code.

~InstallAware Clipboard Data~

~{B1D297ED-E4B3-4434-84AC-3FB3268FD4CC}~

I need this type of comparision because I've the need to remove my software from the Add/Remove applications dialog.

Thanks in advance,

Hi!

The line where you say:

Code: Select all

if Variable SAVEDPRODUCTCODE Equals EPRODUCTCODE

is wrong, it should be:

Code: Select all

if Variable SAVEDPRODUCTCODE Equals $EPRODUCTCODE$

Thanks for the help... Will be buying installaware very soon.

Variables are differentiated from literals using dollar signs.
