Kan niet upgraden naar 5.4.5.1, foutmelding 1500,

vorige installatie blijkbaar niet gelukt, wat nu?

Ik quote een antwoord van het Engelstalige forum
(I have donloaded LibreOffice but it won't install. I get error 1500 saying I'm installing something else when I'm not.)

I’m sorry but the above answer is a bad answer…WAY too complicated and overkill - messing with the Registry and ESPECIALLY reinstalling Windows(?!) is ALWAYS A LAST RESORT!

The problem is that there is more than one MSI installation process going on at the same time. So you need to get rid of the processes conflicting with your current MSI install. I had this problem just now installing LO 5.0.4.2 and here’s how I fixed it:

When you get the error:

  1. Don’t close the install - press Ctrl+Alt+Del and open Task Manager.
  2. Click the Name field to organize your processes with Apps first (at the top) followed by Background Processes (and Windows Processes) below.
  3. Below Apps, scroll down until you find processes NOT in Apps called something like msiexec (I had two in addition to the running MSI install app). These were the culprits on my Windows 8 machine. right-click them and select End Task. Make sure you keep the currently-running MSI install App running of course!

Click Retry or (if I remember correctly) the window should automatically disappear and the install should continue without problems. You DON’T need to reinstall Windows or mess with the Registry!!

Strangely, I did exactly the same thing on a 64-bit Win7 computer and did not have this issue.

Hope this helps!

Helaas, werkt niet, ik laat het maar zo.

Kon je het proces niet vinden in de taakmanager?
