Hi Palcouk,
I'm having the same issue with one of our Win 8 Pro OS users here running Office 365
Here are the two errors and what I've done so far:
Error 1: The required file react-native-win32.dll cannot be found in your path. Install Microsoft Outlook again.
Troubleshooting performed:
- Attempted both quick and online repair (Unsuccessful)
- Attempted re-install of Office 365 twice (Unsuccessful)
- Ran System File Checker (No missing or corrupted files found)
- Checked for presence of file in Office 16 folder. (File is present)
Error 2 (occurs after clicking OK on the above error): The program can't start because api-ms-win-core-version-l1-1-1.dll is missing from your computer. Try reinstalling the program to fix the problem.
Troubleshooting performed (based on a previous post on this site):
- Downloaded the missing dll from https://www.dllme.com/dll/files/api-ms-win-core-version-l1-1-1\_dll.html
- Unpacked the zip file and copied the file into C:\ProgramFiles(x86)\MicrosoftOffice\root*Office16*
Result: While this did remove the error message from both Outlook and Word, in Word the program just closes when attempting to open a blank template
Additional Troubleshooting performed:
Opened Outlook in safe mode (successful)- No error messages came up.
Was there an update or patch pushed through recently?
