Thanks for the feedback
Sometimes a glitch on the line, can cause a small mutation, but that message whilst valid for some broken applications certainly is not normal for Official SumatraPDF.
In the past there have been requests for MD5 or SHA1 testing which can give users some sense of security. However, my opinion is that no hash is better than a compromised one. Thus, I personally consider the best test is one based on herd immunity and often submit suspect files for analysis. One such good utility is https://www.nirsoft.net/utils/hash_my_files.html which allows you to run your SHA-256 result through VirusTotal (however for recent files that have low exposure, results need to be treated with caution).
The downside is occasionally a false positive can be caused by bad analysis
I tried to update v3.1.2 to v3.2 (x64) but the installer crashes with an error (incorrect side by side configuration). Windows event logs do not give enough info to spot the problem. I retried v3.1.2 installer and also the v3.3.12538 pre-release instalers (both x64) and they worked Ok.
Second time of a similar report look at the md5 hash as shown above starts 632416f or check the download direct on virus total and if your file is not Signature Date 2020-03-15 00:42:## then it possibly did not complete well
I just downloaded twice to check both x64 installer links are the same as the original installer and virustotal reports sha 256 as
This problem seems to crop up for short periods see Dec 2017 Download for x64 installer broken
Unsure it it could be periods of high demand or perhaps a bunch of over zealous antivirus checkers b0rking the downloads
Those type of messages usually indicate a failed (partial) download.
seems to cropup in some regions sometimes !
check the downloads against virus total the first SumatraPDF-prerel-13112-64-install.exe if downloaded without failure should be
it is unsigned so may generate some warnings but will run and should show this screen (beware you may wish to alter options,depending on intended users, if more than one user, then set set install folder to Program Files) see the comments above
the 3.2 zip should be
and it should unpack without any problems
Sorry I should have been clearer
the download whilst not detected as a problem is not the correct value for a full download it should read for SumatraPDF-prerel-13112-64-install.exe

the clue yours is not correct is it says you are the first to ask for that file to be tested 1 minute before thus never seen previously (because it is broken)
thank you very much!
I ve installed!
But… to tell the truth I m disappointed
On Win7 the greatest feature (and the only cause) I ve used the Sumatra was locking scrolling down bar to the next page so the only way to go next page was the arrow.
Here on the new version it s not locked - see UPDATE!
Anyway - thank you very much for your quick answer and for my previous user experience
I m very sorry
I do not know how but now the scrolling to the next page is LOCKED!
Exactly what I need!
Thank you very much!
