![]() Chances are the program is either cleaning up after itself, or the parts that remain are required for some reason. ![]() Now, if it’s not clear that a program updates in this manner – a complete download and replacement – then honestly, I’d do nothing. Should you ever need to reinstall from scratch, you’ll have them ready to go. What you can delete is the old download from the original installation, or from the previous update, and this applies only when the program updates itself by downloading an entirely new copy.Īnd for the record, I do recommend that you save at least the most recent download installers, especially for programs that you may have purchased. Note that you’re not deleting the installed program that’s been updated by the new download. When this technique is used, you can typically delete the previously downloaded installer. Rather than just updating parts of the program or patching the program, they simply have you download a completely new version and install it. Other programs, however, often update themselves quite differently. Files are either removed for you at that time or if they’re not, they’re probably needed to keep things working. ![]() This same scenario is also generally true for Microsoft Office: updates are applied to the program directly. If you remove those previous versions with a cleanup, then it just can’t put them back to perform the uninstall. Currently, you can uninstall an update, which basically means that Windows replaces the current updated files with the old ones from the previous version. Two things though: If you’re going to do this make sure to use Windows disk cleanup it will keep track of those dependencies that I mentioned, where a new update relies on an older update.Īnd if you do this, keep in mind that you will be losing the ability to uninstall any updates that remain. If a memory card was used to update the device previously, it may be necessary to format the inserted memory card. It is not recommended to manually move or delete this file. But there’s a a caveat: a cleanup utility – sometimes called Windows Update Cleanup – may have the option to remove prior updates. A missing or deleted map may also be indicated by a missing gmapprom.img file on your device drive or SD card, if inserted. Updates often build upon previous updates, so removing a prior update can sometimes cause problems. The answer to your question really depends on exactly which updates you’re talking about – as well as exactly how they’re delivered and installed.
