[QUOTE="Sebastiii, post: 1154095, member: 60104"] No way to force to use fixed letter drive, i succeed to make it work from powershell but don't succeed to port to C# lol. So i have let the selection to MP config for now and back the old way and it seems but i need to test more than using that code : [CODE=C#] using (var ps = PowerShell.Create()) { // Set mounted ISO file to be able to unmount it if something failed to load. _MountedIsoFile = IsoFile; Log.Debug("Mount-DiskImage {0}", IsoFile); ps.AddCommand("Mount-DiskImage").AddParameter("ImagePath", IsoFile).AddParameter("PassThru"); Log.Debug("Mount-DiskImage Result {0}", psResult.Count); } using (var ps = PowerShell.Create()) { ps.AddCommand("Get-DiskImage").AddParameter("ImagePath", IsoFile).AddCommand("Get-Volume"); var psResult = ps.Invoke(); Log.Debug("Mount-DiskImage Result {0}", psResult.Count); foreach (var driveLetter in psResult.Select(result => result.Members["DriveLetter"].Value.ToString())) { _Drive = String.Format("{0}:", driveLetter); Log.Debug("Mount-DiskImage DriveLetter {0}", _Drive); } }[/CODE] The newest letter drive is always get (result.count = 1). But i fear it's timing issue and then it will failed one day to another or one minute to another lol Attached is the modified file. The first i mount the iso and the second i ask from driveletter, when i use all ps.command in one, sometimes (most of the time), i didn't get result but doing that twice ps.addcommand and it seems to work better. Otherwise the powershell command used to change drive letter : $drive = Get-WmiObject -Class win32_volume -Filter "DriveLetter = 'e:'" Set-WmiInstance -input $drive -Arguments @{DriveLetter="O:"; Label="Label"} We really need to have this syntax : -Filter "DriveLetter = [B]'e:'[/B]" -> 'e:' is the current mounted drive And i change it to O: by -Arguments @{DriveLetter="[B]O:[/B]"; Label="Label"} :p Edit : re-uploaded the zip.
