64bit Host and Quicksupport

Tom_Fox

We have successfully upgraded our 100 Full clients from 32bit to 64bit. One major pain point was copying custom credentials between registry hives. I first needed to backup the 32bit registry settings to a different location, then restore the 3 "MultiPwdMgmtIDs" keys using Powershell.

We also have around 500 Host installations, and around 5000 QuickSupport installations. I recently rolled out a new version of Host and Quicksupport inside my company, to bring all installations up-to-date. On this page (32-bit or 64-bit client - TeamViewer Support) from June it says 64bit upgrades are "coming soon". Do you have any timeframe for this?

If somebody needs help with this, here is the code I used:

First create a copy of the 32bit TeamViewer keys and save these in the 64bit hive. You need to do this BEFORE you uninstall 32bit, as they may be deleted when uninstalling!

reg copy HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\TeamViewer HKEY_LOCAL_MACHINE\SOFTWARE\TeamViewer_Backup /f

The below Powershell checks if a registry backup exists, and if so, copies the 3 keys with custom credentials. You will probably need to restart the computer before these are visible in TeamViewer! For some reason, TeamViewer 64bit doesn't read these on first launch after installation, even if they exist...

$value = Get-ItemProperty HKLM:\SOFTWARE\TeamViewer_Backup -Name "MultiPwdMgmtIDs"

If ($value)

{

  Copy-ItemProperty HKLM:\SOFTWARE\TeamViewer_Backup HKLM:\SOFTWARE\TeamViewer -Name "MultiPwdMgmtIDs"

  Copy-ItemProperty HKLM:\SOFTWARE\TeamViewer_Backup HKLM:\SOFTWARE\TeamViewer -Name "MultiPwdMgmtPwdData"

  Copy-ItemProperty HKLM:\SOFTWARE\TeamViewer_Backup HKLM:\SOFTWARE\TeamViewer -Name "MultiPwdMgmtPwdDataDate"

}
