Can I install both keil-ver4.74 and keil-ver5.12 on one windows 7 system?(for some old projects I need ver4.74).
Is there any problem ?
Can I work with both of them?
I hope you do version-control your project files too - then you can recover if you accidentally opens an older project (intended to stay with the older tool chain) and Keil decides to update the project files.
