I'm trying to bring up a C51 project from a couple of years ago in uVision. All looks OK initially, but the Build option is greyed out.
It's as if it lost its brains about using the C51 compiler.
Can anyone offer insights as to how to diagnose this issue?
I bought a "Perpetual" license for PK51 back in 2019 and it shows in the License Manager that support expired at the end of 2020. But I know I used it successfully early last year.
I tried installing the latest version of uVision, but the system won't let me download it since I'm outside the support period.
Any help would be appreciated.
Thanks.
Whenever I encounter a software problem, my instinct is to install the latest version. It sounds like that instinct screwed me here.
Are older install packages available?
Nevermind. I found an old install package and now things seem to be working well...
I wrote in my last message: "You can only download and use the MDK versions...". Of course I meant "… use the PK51 versions...".

In general, there's nothing wrong with this approach, but the support period must not be expired for this.

Yes, they are! As my colleague already explained, go to the page https://www.keil.com/download/product/, enter your serial number and you get a list of all PK51 versions that you can use with your license.
