Hello everyone,   I try to install a pulse secure application, modified by my university, which could not help me so far. During the installation, the installer aborts and gives the following Errormessage:   Error 1720. There is a problem with this Windows Installer package. A script required for this install to complete could not be run. Contact your support personnel or package vendor. Custom action writeTncConfigFile.D7CCF602_E814_4416_8EC5_24D6FEA3289C script error -2146828212, Laufzeitfehler in Microsoft VBscript: Der Pfad wurde nicht gefunden. Line 10, Column 9,   The comment is german for "Runtime Error in Microsoft VBscript: Path not found"   The error happened during an Update. Uninstalling the previous version did not work.
