I have V1.2 installed but also need V1.0 installed to be able to produce lip sync files for the voice overs.
But when I try to install V1.0 of the CS it asks me if I want to uninstall V1.2,if I click "No" it just ends the install prog.
How can I have both versions installed at once to be able to use both versions.?
I have read the wiki info and it states that both versions can be installed and used.
Where am I going wrong.?

This is what I usually do:-
This is what I usually do:
- Install TESConstructionSet_v1.2.000.exe
- Rename the old TESConstructionSet.exe to TESConstructionSet_v1.2.000.exe
- Install TESConstructionSet_v1.2.404.exe
- Remove the old version, when asked (the old .exe will stay as it is renamed)
- Rename the new TESConstructionSet.exe to TESConstructionSet_v1.2.404.exe
Now you will have the old and new ConSet installed.
