The uninstall files have been purged from your server for Composer 6.2.2. You will need to locate the Composer 6.2.2 installer and extract the files. Then you can browse to the directory of the files you extracted and select them during the upgrade.

It does not work, it's looking for a msi. and the installable vmware is exe ...

It seems that initially after installing the composer, the installation file has been deleted. This is the only reason you are getting the error.

As a workaround:

• uninstall View Composer Application 6.2.2 only from Program & Features  ( NOTE: Do not remove or delete the Composer Database)
• Re-install View Composer Application 6.2.2 again pointing to the existing Composer Database.  ( This will make sure you have the installer file)

There after you can perform the update.

NOTE: Even though Composer DB is not touch, please take a backup of the composer database prior performing the action plan.

If the above steps is helpful, please mark the answer as correct

I'm sorry to answer late, called the vmware technical service and it was exactly this. Thanks
