This is driving me crazy, because I have other code in the same installer that works just fine when using RenameFile() to move folders and their contents (subfolders and files) to the backup folder. For some reason, this code doesn't work, and I have no idea why. I've tried creating the backup folder before the RenameFile() operation too, and the folder is created, but RenameFile() still doesn't work. In the following code, the messages for the "Base source path is " and "Base target path is " are displayed, and the paths are correct. Then I just get the message "Could not move [folder2] to [folder2]" because RenameFile() failed. Why?
//----------------------------
// Backup and restore Help
//----------------------------
function BackupRestoreHelp(BackupDir)
STRING SrcPath, TargetPath, HelpFiles;
begin
Disable(LOGGING);
if (!MAINTENANCE) then
SrcPath = TARGETDIR;
TargetPath = TARGETDIR ^ BackupDir;
elseif (REMOVEONLY || REMOVEALL) then
SrcPath = TARGETDIR ^ BackupDir;
TargetPath = TARGETDIR;
endif;
MessageBox("Base source path is " + SrcPath, INFORMATION);
MessageBox("Base target path is " + TargetPath, INFORMATION);
// Move the Help files
HelpFiles = "help\\AppHelp";
if (RenameFile(SrcPath ^ HelpFiles, TargetPath ^ HelpFiles) < 0) then
MessageBox("Could not move " + SrcPath ^ HelpFiles + " to " + TargetPath ^ HelpFiles, SEVERE);
abort;
endif;
Enable(LOGGING);
end;
