# Frequently Asked Questions ## 1. Why am I getting Error Code: `105035` while using Windows SDK? In most of the cases, this is caused by re-signing or adding new signature to the following files while integrating and deploying our SDK: - **CptControl.exe** - **CptHost.exe** - **CptInstall.exe** - **CptService.exe** - **CptShare.dll** - **zzhost.dll** - **zzplugin.dll** - **aomhost64.exe** Please **skip signing as well as adding new signatures** to the above files to prevent this error. If you encounter this error code even when the above files are not being re-signed, visit the [Zoom Developer Community Forum](https://devforum.zoom.us/) and let us know how we can help.
