The exactly same problem on Maple 2022 (Linux)...!!??

On-line help for Maple 2022 is still not available.

Moreover, PDF documentation is available only for Maple 2021, too. Programming guide for Maple2021 is actually still in version for Maple 2020.

Is that normal???

I am really very interested about any future plans regarding multi-precision evaluation speed up. I think, fast multi-precision evaluation is really one of most important feature of any modern CAS. And Maple is still (as I said on this forum several times together with relevant links to benchmarks) very slow.

@tomleslie Thanks for help! The problem was some mismatch between two versions installed together (2021.2 + 2022.0) and between two corresponding  license files located at specific user defined directory.

==================================================

Something is completely wrong ... :(

Still no progress with terribly slow multi-precision evaluation of function and linear algebra.

Question: Are there any plans for significant improvements?

I would like to see significant improvement of multi-precision evaluation speed (elementary + special functions and linear algebra, at least). See, for example, the comparison here and here It is a bit old, BUT still relevant (Maple 2021). Maple is permanently terribly slow even in quadruple precision case!!! 

P.S. A year ago, I asked for the same ... here

@ecterrab Yes, the problem is fixed now ... thanks!!!

@ecterrab So the problem really exist, users should install updates via Maple Cloud and ignore the absence of update announcements. 

@Thomas Richard Still no Programming Guide for recent Maple version??!!

@Thomas Richard Thanks for a positive replay :)

@acer  My question is about the specific case when the symbolic Sum experession range N is not a numerical value!

When will be available updated manuals for maple 2021??? So far are available only manuals for Maple 2020 (see here).

@Thomas Richard Well OK ... good news. Could you provide detailed steps how to install and configure GCT on single machine? All info at the documentation is only for network (multi-node) case.
