Lotus Installation Question

When using a transform file to affect an install it only works when applying it to a new installation. For an existing installation it will not overwrite certain settings such as single sign on or icon removal.

How do I apply the transform file so that it will overwrite the existing settings with new ones.

I’m using

setup.exe /s /v" TRANSFORMS=tampa.mst /qb"

I’ve also tried the same thing with a /A

If its a new installation the transform file works.

If its an existing installation it upgrades but it keeps the same settings, and doesn’t apply the new settings changes.
