Error installing SolrServer 12.1

Installing SolrServer on a test\dev separate server, and getting the following error:

java.nio.file.FileSystemException: C:\Users\aaworourke\AppData\Local\Temp\2\PTCSOLNINSTALLER_PtcInstall.log: The process cannot access the file because it is being used by another process.

According to Task Manager, nothing is running connected to Solr. We are using Amazon Corretto 11 for our java environmental variables. Just curious if anyone else has seen this. Many thanks in advance!
