C# Make application compatible on other computers? -

edit: here file if want test: cleaner

i'm making program cleans files automatically @ startup performance reasons.

how make application work on computer has release files?

i made application using framework 2.0 , works correctly without errors on computer if copy release files computer, "application stopped responding" happens when starts.

there no resource files except icon , embedded resource. have no idea do.

    private void cleansystem()     {         timer1.enabled = true;         timer1.start();         progressbar1.maximum = 10;         string offline = environment.expandenvironmentvariables("%systemroot%") + "\\offline web pages";         string download = environment.expandenvironmentvariables("%systemroot%") + "\\downloaded program files";         string software = environment.expandenvironmentvariables("%systemroot%") + "\\softwaredistribution\\download";         string wintemp = environment.expandenvironmentvariables("%systemroot%") + "\\temp";         string recent = environment.expandenvironmentvariables("%appdata%") + "\\microsoft\\windows\\recent";         string cookies = environment.expandenvironmentvariables("%appdata%") + "\\microsoft\\windows\\cookies";         string tempinternet = environment.expandenvironmentvariables("%userprofile%") + "\\local settings\\temporary internet files";         string apptemp = environment.expandenvironmentvariables("%userprofile%") + "\\appdata\\local\\temp";         string settingtemp = environment.expandenvironmentvariables("%userprofile%") + "\\local settings\\temp";         emptyfoldercontents(offline);         emptyfoldercontents(download);         emptyfoldercontents(software);         emptyfoldercontents(wintemp);         emptyfoldercontents(recent);         emptyfoldercontents(cookies);         emptyfoldercontents(tempinternet);         emptyfoldercontents(apptemp);         emptyfoldercontents(settingtemp);         timer1.interval = 1000;         timer1.tick += new eventhandler(timer1_tick);     }      private void emptyfoldercontents(string foldername)     {         foreach (var folder in directory.getdirectories(foldername))         {             try             {                 directory.delete(folder, true);             }             catch (exception excep)             {                 logger.fatal(excep);             }         }         foreach (var file in directory.getfiles(foldername))         {             try             {                 file.delete(file);             }     catch (exception excep)     {       logger.fatal(excep);     }         }     }     void timer1_tick(object sender, eventargs e)     {         if (progressbar1.value != 10)         {             progressbar1.value++;         }         else         {             environment.exit(0);         }     } }

i try change code in way

private void emptyfoldercontents(string foldername) {     if(directory.exists(foldername)     {         foreach (var folder in directory.getdirectories(foldername))         {             try             {                 directory.delete(folder, true);             }             catch(exception ex)                             {                  messagebox.show("error deleting folder: " + folder+ environment.newline + ex.message);             }         }         foreach (var file in directory.getfiles(foldername))         {             try             {                 file.delete(file);             }             catch(exception ex)             {                  messagebox.show("error deleting file: " + file + environment.newline + ex.message);             }         }      } 

}

i have added minimal check see if directory exists, keep in mind code fail large number of reasons. look @ exceptions list on msdn documentation
