Context menu in file-open/save dialogs on x64 OS. On x64 versions of Windows 7 and 8, the TortoiseSVN context menu and overlays won't show for 32-bit applications in their file-open/save dialogs until you install the 2022 C-runtime for x86. (select the vc_redist.x86.exe file for download).. Note: this only applies to 32-bit applications on x64 OS.
