Yes, there is, @txssound. I can share the link for downloading the R11 release patch for Quickbooks Point of Sale (QBPOS).

Since QBPOS v18 is no longer available for download on our website, you can go to this link to download the patch for the R11 release: https://qbpos.intuit.com/POS18.0/WebQBPOSPatch_V18R11.exe.

The reason why you're unable to update your QBPOS is that it is no longer supported by Intuit. If you wish to update it to the latest release (R15), use this link: https://qbpos.intuit.com/POS18.0/WebQBPOSPatch_V18R15.exe.

Additionally, you might want to consider Shopify as an alternative POS solution. For more information, you can visit this link: Shopify.

You can always visit the Community page for clarifications or further concerns about installing QB POS v18 updates. We'll be glad to address your queries. Take care and have a good one.
