# Common problems/troubleshooting¶

Prebuilt installer:

• Because the RAW team is an ‘unknown’ developer, you will probably see some security warnings when you install RAW. When you do, just give the installer and program permission to run on your computer.
• RAW is used by (relatively) few people, which means some antivirus programs may not have seen the RAW software before. Occasionally virus scanners will mark a file (typically RAW.exe) as a threat (it will usually be in the ‘general malware’ category). If this happens, please do the following:
• Upload the file to https://www.virustotal.com/ and see if any other antivirus programs identify it as a problem (it is always possible someone hijacked the installer somehow!).
• If most or all of the antivirus programs on virustotal.com clear the file, make an exception for it in your virus scanner.
• Contact the RAW developers, so we can report the false identification to the virus scanner company and get the file whitelisted in future definitions files.

From source:

• If you are updating your RAW installation, you should completely delete the old RAW source files, and then replace them with the new ones.
