[wpkg-users] WPKG client upgrade

[Vladimír Pšenička]

When I upgrade WPKG client this way (without "start"):

> <upgrade cmd='%COMSPEC% /C "%SOFTWARE%\wpkg\wpkg_upgrade.bat"' /> 

it doesn't work, on client I see errors:

> Product: WPKG -- Error 1722. There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor.  Action _25773255_2E4C_4B11_9B7E_FF3EB8BD0D64, location: C:\Program Files\wpkg\WPKGSrv.exe, command: /install 

and:

> Could not process (upgrade) package 'WPKG Client 1.2.1' (wpkg):
> Exit code returned non-successful value (1603) on command '%COMSPEC% /C "%SOFTWARE%\wpkg\wpkg_upgrade.bat"'.

and before this 2 errors some message that says:

> Produkt WPKG: Soubor C:\Program Files\wpkg\wpkglogon.dll je používán jiným procesem (Název: winlogon , ID: 648).

wpkglogon.dll is used by another process (winlogon)
