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?
Be very very careful about using both versions on the same machine
Version 5.12 modifies the project file and tries to assert "PACK" settings for clk speeds and start vectors etc if you accidentally press the wrong thing.
I have had a nightmare three days trying to get a previously stable project to run. ( builds fine but does not run or debug. e.g. on debug it doesn't reset back to the start vector run pass main etc)
Yes I had the legacy support loaded
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.
