After the initial release of Intel® Parallel Studio XE 2020 Update 1 build 085 we found a bug in our installer. It affects only the installer. We republished Intel® Parallel Studio XE 2020 Update 1 for Windows* with a new package, build 086. Intel® Software Manager (ISM) for Windows will detect this and alert you to a new update. Updating is optional, as other than the installer builds 085 and 086 are identical. You may wish to install the newer build 086 so that ISM will not alert you about this update again in the future. We apologize for the inconvenience and redundant notices in ISM.
