I am getting a Checksum error when unpacking the PS2018 download. If I try doing the install where I choose what components I want, it brings up the splash screen and then goes away and I get nothing. I have tried 2018 and the update 1 for 2018 and I get the same problem on both.
They used to publish file size and CRC-32 checksum information for the Parallel Studio installers, for example, https://software.intel.com/en-us/articles/intel-parallel-studio-xe-2017-checksums . I cannot find similar data for the current version.
Are you unpacking it yourself, in preparation for offline or silent installation, or are you executing the installer directly?
In the past I have suggested deleting the downloaded file, clearing the browser cache, and downloading again. Intel offers both an "online installer" and a full download - whichever one you tried before, try the other.
Try temporarily disabling any anti-malware program you have running and then try an install. It is possible you have some other process that is corrupting the files.
At this point I suggest submitting a support request to https://supporttickets.intel.com/?lang=en-US Check your Windows event log to see what it reports for the reason the installer closed, if it does.
You never said what you meant by "get an error", though.
