When trying to reinstall Internet Explorer you may receive the following error message:
Setup could not verify the integrity of the files needed for Installation. Make sure the cryptographic service is running on this computer.
No matter that you’ve restarted cryptographic service, you are still receiving this message.
To fix this please do the following:
Hit Win ORB | type: inetcpl.cpl | Advanced tab | Click on the ‘Reset’ button to reset IE settings
If that didn’t help, please do the following:
Hit Win ORB | type: cmd ; right click on cmd and select ‘Run As Administrator‘
Now type these lines one by one by pressing Enter after each line.
regsvr32 softpub.dll
regsvr32 wintrust.dll
regsvr32 initpki.dll
regsvr32 dssenh.dll
regsvr32 rsaenh.dll
regsvr32 gpkcsp.dll
regsvr32 sccbase.dll
regsvr32 slbcsp.dll
regsvr32 cryptdlg.dll
Try to run the IE installer again. If you still have integrity issues, please post your comment below and I’ll try to help.
