Hi guys,
it's me again. today i'm trying the "Process" class.
I'm trying to uninstall one product developed by my company thorugh
..net code but it seems not working but when i execute the commandline
MSI uninstall command it seems working fine. the code i'm using is:

System.Diagnostics.Process p = new System.Diagnostics.Process();
p.StartInfo.CreateNoWindow = true;
p.StartInfo.FileName =
Path.GetFullPath(System.Environment.GetEnvironmentVariable("WINDIR") +
"/system32/msiexec.exe");//Environment.GetEnvironmentVariable("WINDIR")+
"/system32/msiexec.exe";
p.StartInfo.Arguments = "/uninstall " + new
FileInfo(powerlearn.MSIPath).Name + " /qn";
p.Start();
p.WaitForExit();


whenever i execute the code, it does nothing. i mean i tried to debug
this code but when i came to "p.WaitForExit();" and i pressed the F10
it moved to another line without waiting process to be completed. seems
that process is somehow not able to run.

can anyone help me out from this problem? any other solution is also
welcome.

Tools:
c#.net 2.0 (VS.NET 2005)


Thanks,
Lucky

I forgot to add some information.

when i start the process it exits in a second and returns ExitCode :
1619

i hope it would help more.

thanks again,
Lucky

Hi guys,

it's again me. i found the solution of my problem.
there are to ways to do it.

1) in the Arguments pass the fullname of the FileInfo object rather
then only file name
2) keep the code as it is and change the directory to file directory
where the file is, before this code.

it is all about telling msi the full path of the s/w msi file. it
doesnt matter wihch way u do it. you only needs to tell it where is
that file.

by the way. thanks for reading.

Hello Lucky,

Actually, it does matter how you do it.  Unless you set the working directory
back after you are done.. things may not work as expected.  Given a choice,
you should always opt to pass the full path rather than change the working
directory.
