Setup problems with Internet Explorer 11

Installing Internet Explorer creates the following log files, which are stored in the Windows installation folder (typically, the C:\Windows folder):

• IE11_main.log

• IE11_NR_Setup.log

• IE11_uninst.log

• cbs*.log

• WU_ IE11_LangPacks.log

These log files continuously record the entire process from the moment the IE setup program starts running until the last .cab file is downloaded, including error codes. The possible error codes are:
