[GNC] Updated from 5.12 to 5.13 but cannot open GNUCASH any longer

[Joseph Hymel]

Running Win 10 on desktop
I installed 5.13 just as I done every time for over 6 years now. After install completed and I tried to open GNUCASH, I got these two notification message boxes:
"The procedure entry point clock_gettime32 could not be locatedin the dynamic link library c:\\Program Files (x86)\gnucash\bin\libstdc++-6.dll"
"The procedure entry point pthread_cond_timedwait32 could not be located in the dynamic link library C:\Program Files (x86)\gnucash\bin\libjavascriptcoregtk-3.0-0.dll"
I have a backup copy of all the files generated after each use of gnucash on daily basis. I need help and am not a computer technical expert. I am just a user of gnucash.
