In the good old days it was quite normal to use an external VBScript which ran xacls.exe or something similar, to set permissions on files and registry keys that were included in your msi-file. Setting these permissions using the ‘LockPermissions‘ table was not recommended.

One of the problems facing when you used the LockPermissions table, was that permissions on already existing local files were simply overwritten and were not added/merged with the already existing permissions on these files. Another limitation was that it didn’t natively localized user groups based on well-known SIDs. When you e.g. were setting permissions on the ‘Users’ group and ran the msi on a Russian Win7 system the msi would fail to install, because it didn’t know of a usergroup called ‘Users’. In Russian the group is called ‘Пользователи’. You would receive error message 1609 “An error occurred while applying security settings. Users is not a valid user or group. This could be a problem with the package, or a problem connecting to a domain controller on the network. Check your network connection and click Retry.“ There was a way to solve this with a special mergemodule called SIDLookup, but not everyone knew of its existence.

Since Windows Installer 5.0 (included in Windows 7 by default) there is a brand-new table called ‘MsiLockPermissionsEx‘ which can be used to set permissions on files, registry, folders, and services that are installed with your msi-package. You can find the TechNet page explaining all this here:

Today was finally the event I was looking forward to for months: the 1^st European App-V user group meeting. After 4 German User group events (Cologne, Munich, Hamburg, and last month in Berlin) it was now time for the European edition organized by the App-V user group. These meetings are by the community for the community. The German events were in German language and at this event – as it was for the European community – all the sessions were in English language.

Only 2 weeks after registration for this event had opened, the organization had to tell people that it was no longer possible to register, because there was no more space. But next year there will be another event – in Amsterdam again (at the Sheraton Hotel which offers space for over 350 people). Today there were about 120 people at the event.

Not only for the sessions itself it was useful to attend the event, but also for networking and meet other people that are obsessed in some way by App-V.

To give you some idea of the high quality of the event: there should have been 9 App-V MVP’s – unfortunately 2 had to cancel their visit at the last moment – but that still is quite extraordinary, as there are only 16 App-V MVP’s worldwide!

Not only people from Holland visited the event, but also people from countries like Belgium, Germany, UK, Ukraine, Norway, Sweden, and many more countries. Lees meer (0 reacties)
