Files cannot be deleted from the XL library?

[amylanza]

I have the syntax as follows:

libname xl xlsx "insert path here.xlsx";

proc sql;

drop table xl.tablename;

quit;

data xl.tablename;
set differenttablename;
run;

I am getting the error: 

ERROR: XL.tablename.DATA cannot be deleted because files cannot be deleted from the XL library. 

I did not have an issue with this prior to a recent upgrade to this version of SAS. I am working in SAS EG 7.1. Has the syntax changed? What is this error?

Might want to check file settings for write, or the folder permissions.

If you or someone else downloaded the xlsx file it may have been set as read only during the download process or some other protection feature implemented. Go to the file menu in Excel and examine the properties and adjust if needed.
