This is an insidious one for sure.
Some installs have a left-over entry in the HIDDEN ''**c:Program filesZero G Registry**'' folder.
The file is called:
Look at the XML file there (with an XML editor like Notepad++) and you will see an entry for a product ''HP Application Lifecycle Management''.
It's name tag will look something like this:
> name=''HP Application Lifecycle
If this is the ONLY product entry, you can just DELETE the entire XML file, but if there are other entries there (for other products), you should just delete the entire ''product ... /product'' tag/section relating to ''HP Application Lifecycle Management''.
After this file has been modified or deleted, try the install again.
