Currently, we cannot push out the 3CX Windows client in larger organizations using Group Policy or other environments when the end user does not have Local Administrator rights. This is due to the dependency on Visual C++ Redistributable, which can only be installed using an Installer, and that requires Local Admin rights. Please create a secondary 3CX Client installer with the required Visual C++ DLLs placed into the the 3CX application local folder, so that the separate installer is not required. https://docs.microsoft.com/en-us/cpp/ide/redistributing-visual-cpp-files This will allow organizations to push the 3CX Windows client to workstations without user intervention or local admin permissions. They will simply need to open the provisioning file. Maintaining the current distribution will allow organizations that prefer to maintain a single set of VC dlls for all applications to do so.
