ModeratorHi @SHard2,
Noted with thanks on the details explanation, yes current we do see that there are some isues with updates on WSL.
For NIOS II Build Tools 19.1, here is another recommended workroaund which perhaps you can try and see hope it help:

As for access denied error on NIOS II build tool 18.1 build 646, there seems to be another known similar error which the workaround is to used the older version of 18.1 build 625. (https://www.intel.com/content/altera-www/global/en_us/index/support/support-resources/knowledge-base/tools/2020/why-do-i-get-error-when-creating-a-new-project-with-nios-ii-ecli.html)
On the final part mentioning the support of Stratix IV in Quartus Prime Pro, is that the DSP builder that you are referring to? I did mananged to check on the Handbook for DBP Builder, it seems to be supporting Stratix IV. Hence just curious, can you please help me to understand by further eloborating on what are the non supported feature mention?
Warm Regards.
Occasional ContributorHi
I have asked in a previous support request to Intel about support for DSP Builder in 20.1 STD, I was informed that from 20.1 onwards it was no longer supported. This prevents me upgrading beyond Q19.1, as I must support Stratix IV which therefore limits me to the STD product.
Secondly, the work around you mentioned for Q19.1 does not work. Certainly not when I tried it.
The NIOS tools worked correctly in Q19.1, using WSL1, until what I understand was a windows update. After this point the NIOS II toolchain no longer worked, as described in a number of support requests. The workaround you mentioned just clarifies that 19.1 does not work with WSL2.
