In addition to the already publicised BAD installation practise this steals and distributes illegally an old GPLv3 build of FFMPEG.EXE and binaries to do the screen capture and encoding in their closed source product whose license model is incompatible with the GPLv3 license. ZD Soft produce a proper installer that requests elevated rights or is in a form that can be run with admin rights to permit installation in the proper location or optionally a non-system drive. Even MSI installers can and should request rights elevation IF they are compiled properly, which obviously yours are not compiled properly. Try again!
In the mean time we can work around this faulty MSI by following the instructions in the article at:

I found the advised default command string value did not work and I had to use:
“C:\Windows\System32\msiexec.exe” /i “%1” %*
That shows us how to add an install as administrator option to the MSI file types context (right click) menu. Then we can select C:\Program Files\Screen Marker\ to install the program properly!
Then it worked with this MSI file. I also note that on launch this supposedly simple screen marker runs msedgeview2 browser engine to make numerous unsolicited IPv4/IPv6 web requests which can be doing anything… I let my Malwarebytes windows firewall control block all those requests as there is no legitimate reason to permit them and ultimately blocked them permanently. And only allowed ScnMkr.exe through to validate the giveaway license key which worked.
HTH and makes it past any URL posting filters.
