Silent uninstalls not working

[datamagnet]

I am having a problem.

I make a setup package called myAppSetup.exe with installshield express2008 and everything installs just fine.

I want to do a silent uninstall and am trying to use the MsiExec.exe /x {ProductString}/qn at the winXP Start|Run command line

I keep getting an error message that it cannot open the msi file.

If I run it just as MsiExec.exe /x {ProductString} then I get the dialog boxes and I can uninstall using them.

What am I doing wrong?

Any help appreciated.

My MsiExec.exe is - Windows ® Installer. V 3.01.4000.1823

Put the space between package code and options ...
MsiExec.exe /x {ProductString} /qn
