# 372 Executing a Restructure From a Read-Only (CD-ROM) Device Causes Error

---

This application contains a large number of records and runs from a CD-rom. To save preferences, ... I have to create 3 tables on the C-drive of the target PC. I used the reverse engineering tool from DBIsam to create the pascal code. Now when I run the application from my harddisk, everything goes well, the files are created and the application boots correctly. When I run the application from a CD. I get an error message 'DBIsam Engine Error #11013 Access denied to data file I:\TMP0.DAT'. I do not have a file named TMP0.DAT in my database tables, so I suppose this is a temporary table used by Dbisam when creating the tables. The I drive is my CD-rom.
