How can we perform a silent install of Mychat 8.13+ via command line in “Program Files” after the update change in version 8.13 ?
We tried to install both versions in “c:\Program Files” and encountered some issues:

MSI installer :
- we changed the default installation directory via MSI transform file
- running the shortcut on desktop from other account then the account used to install, causes a start/repair/finishing MSI installation

EXE installer:
- we changed the default installation directory via dir parameter
- for /silent or /verysilent installation the deinstallation information in Windows registry is saved in HKEY_USERS registry hive (the account used for installation) and not in HKEY_LOCAL_MACHINE registry hive (assigned to SYSTEM/computer)
- performing a manual installation (manually selecting all options in installer, including Install In ‘c:\Program Files‘) correctly registers the deinstallation in HKEY_LOCAL_MACHINE registry hive

In our environment the preferred method is to install in ‘c:\program files’ and preinstall the client for our users before first use. We use a third party tool, which doesn’t have the possibility to run in user context.
Can you propose a method of silent installation in “Program Files”, so that it would behave the same way as in previous versions ?
Can you make a second installer (or implement additional parameters) which would correctly perform an installation in ‘c:\program files’ (as in previous versions) ?
Please check/fix/confirm the listed problems.

Best regards,
Luke

Hello, sorry for the late reply.

OK, we will work on EXE installer to be able to install it in a silent mode (the key /silent or /verysilent) in Program Files and write data in the HKEY_LOCAL_MACHINE. We will try to make possible it the next version.
