If the installation fails when installing eclipse with the message: "Failed to install eclipse.Cannot recover from this error.", take a look at the install log and search for _JAVA_OPTIONS.Note that launching CCS with '-clean' will cause the launch time to be slower so it is not recommend to use it every time but only when needed. Clean the workspace (or try using a new one): CCS stores various information in a folder called '.metadata' located in the user's workspace.

an internal error occurred during updating location information-53

Then download and install those libraries from Microsoft's download site.

If using CCS 6.2.0.00050 also uninstall and reinstall 20 MSVC Redistributables.

If that does not help, try removing the line "256M" (or equivalent) just after "--launcher. Some antivirus/security software are more aggressive than others and may block CCS for starting up.

Try disabling it and see if that allows CCS to start.

Use the -clean argument when calling ccstudio.exe: CCS is launched by running the '.\ccsv6\eclipse\ccstudio.exe' executable.

This is what is called when using the CCS desktop shortcut.

However, can be called with some command line arguments. When calling 'ccstudio.exe' with '-clean', it will clean out cached data by the IDE and plug-ins upon launching CCS.

Sometimes this cached data can get corrupted over time and cleaning it out can fix many problems.

The CCS installer needs to be able to write to a temporary location and execute programs from it.

By default, it uses the system temporary directory %TEMP% but if that directory does not have the right permissions, the installation will fail with the above error.

If so, it may be necessary to add some exception to the software to allow CCS to run properly CCS has a dependency on some Microsoft runtime libraries.
