Hello,

I have MyDac and today I installed Unidac.

When Delphi 2010 starts I get a lot of error messages as:
entry point couldn't be found @Memutils@IsClass$qqrp14System@TObjectp17System@TMetaClass in dac140.bpl

And the final messege: "Class TMyQuery not found" <- this WAS the MyDac query.

What can I do so as BOTH components would work? Obviously if I have 50+ softwares with MyDac, I don't want to change them to UniDac. The Unidac would be only for non MySql databases.

Thank you for your help

Such problem shows that you are using incompatible versions of MyDAC and UniDAC. Product compatibility is provided for the current build only. To make MyDAC and UniDAC work simultaneously on the same IDE, you should use the compatible versions of them. The latest compatible versions are the following: MyDAC 7.5.9, UniDAC 4.5.9.
To solve the problem, you should perform the following steps:
- close Delphi 2010;
- uninstall MyDAC and UniDAC;
- remove all *dac*.bpl and *crcontrols*.bpl files from your computer;
- remove *.dcu files from your project;
- install MyDAC 7.5.9 and UniDAC 4.5.9 .
