Many Excel users will open new Excel sessions each time a new workbook is opened via double clicking on a workbook link. The easiest way to run out of memory and get the message 'Excel can not complete the task with available resources.' is to have 1) Multiple Excel sessions open and 2) other applications open.

If you are using Excel 2010-2021, click File, Options, Add-ins, change the dropdown box to COM add-ins and click Go.If you are using Excel 2007, click the round Office Button, Excel Options, Add-ins, change the dropdown box to COM add-ins and click Go.If you are using Excel 2003, download our free Add-in Information Lister and use it to un-install the COM add-ins.

Two frequently mentioned as problems are Blue-Tooth and Adobe COM addins.

COM add-ins are often reported as causing memory problems (our add-ins are not COM add-ins). They are often installed without explicit approval. COM add-ins are a special type of add-in written in machine language. The number one thing you can do: If you have any COM add-ins installed, un-install them unless they are absolutely required. We have tried to order the steps from easy to do to hard to do. Memory problems are often difficult to solve. It is also possible that none of these steps will solve. The following are steps one can take that may solve memory problems. We have had all of our add-ins open at one time and no memory issues. VBA add-ins (the kind we write) are not compiled and are called Excel add-ins and do not cause memory issues.Ususally you can run one COM add-in without issues. Often at the expense of Excel, especially if they are badly written. COM add-ins are compiled computer code that manages their own memory.We have never seen a need for them in Excel. The two COM add-ins we have seen that cause memory issues are Adobe and Blue Tooth.COM add-ins sneak onto your PC without permission (or clearly asking).The conclusion we reached from the much testing is that COM add-ins are the major cause of memory issues. This re-write appears to have affected memory usage. Microsoft re-wrote large portions of Excel when they released 2007. Excel 2007-2021 users tend to see them more than Excel 2003 users. Resources or Excel can not open workbook with available resources. Microsoft Excel users will sometimes get a message that says their computer is out of memory, enough system resources toĭisplay completely, cannot complete this task with available What to do if you get an out of memory or not enough resources message
