Today I encountered an unusual problem with a client who use IE8 to use a legacy system which is browser specific. # The Problem So errors such as the following occurred when using internet explorer. - “Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found” - Unable to download files. - In internet options -> temporary internet files: disk space is configured to 0 and the current location of the cache is blank and cannot be changed. - “There won’t be enough space in the new location for the currently downloaded content. Please either delete these files first and try again, reduce the size of the folder, or pick another location.” whilst trying to change the directory of the temporary files. # The Cause Internet explorer was downgraded from a higher version to IE8 to ensure compatibility with this legacy system and registry settings were corrupted in the process. The easiest way to fix this is using the following steps: 1. Close Internet Explorer. 2. Run Regedit 3. Navigate to: **HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\InternetSettings\5.0** 4. Export the **Cache** and** LowCache** branches as a backup. 5. Delete **Cache** and **LowCache.** 6. Open Internet explorer – the keys will be automatically recreated with the default values. --- [[Epistemic status|Colophon: Brewed]]
