List of all Addin MSI Installer parameters:

Installation from the command line (elevated mode)
Normal mode
When installing for the first time:
msiexec /i [path Addln.msi file]
To change the default key values at the first installation, use the prompts as described in the "Update" part.
The default Addin language is English, but it can be changed to German, Italian or French. To set the
language at the first installation, enter the following on the command line:
msiexec /i [path Addln.msi file] EXPAMLANG="GE" - German
msiexec /i [path Addln.msi file] EXPAMLANG="FR" - French
msiexec /i [path Addln.msi file] EXPAMLANG="IT"- Italian
NOTE: EXPAMLANG="EN" stands for English
The registry language, i.e. the language of application in the user's mailbox and the installation language,
can differ. Use the EXPAMLANG prompt to set the registry language (as illustrated in the above examples)
and TRANSFORMS the to set the language for installation. Enter:
TRANSFORMS="1031.mst" for German
TRANSFORMS="1036.mst" for French
TRANSFORMS="1040.mst" for Italian
NOTE: TRANSFORMS="1033.mst" stands for English
Example:
msiexec /i [path Addln.msi file] TRANSFORMS="1031.mst" EXPAMLANG="FR"
- if you set parameter TRANSFORMS="1031.mst" EXPAMLANG="FR", only the setup language will be German, but the registry language key (HKEY_LOCAL_MACHINE\SOFTWARE\Metalogix\Addin) is set to French ("FR"), so the Addin language in the user's mailbox will be French.
Update
add to the command line when you are updating
or
REINSTALLMODE="vomus"
Example:
msiexec /i [path Addln.msi file] REINSTALLMODE="vomus"
msiexec /i [path Addln.msi file] EXPAMSERVER="<PAM4exchangeServerName>" REINSTALLMODE="vomus"
NOTE: You can use also silent installation (see "Silent Installation").
Example with registry key changes (see Firuge 3):
msiexec /i [path Addln.msi file] REINSTALLMODE="vomus" EXPAMSERVER="<PAM4exchangeServerName>" EXPAMLANG="GE" TOTALDISABLEADDIN="0" TOOLBARENABLED="1" APUBLISHPFORMS="0" PUBLISHVISIBLE="0" USEPROXY="1"
(Updates Addln and changes the selected PAM4exchange Addln registry keys default values to your desired ones.)
Uninstall Addin
To completely uninstall Addin, enter:
msiexec /x [path Addln.msi file]
NOTE: Silent mode is also possible.
