Paste Problem from Excel 2010 to PowerPoint 2010

Hello, I have developped an Excel(2013) tool that generate a PPT Presentation.
My client has Excel 2010 and the tool doesn't work.
I have tried to find the error and it seems that it has to do with the way I paste the tables/charts using the slide.shapes.paste.select code.
So I tried to pastespecial using the enhancedmetafile and it worked but I don't like the format on PowerPoint.
My question is: am I obliged to do this for Excel 2010? or is there a way to paste normally like I do on Excel 2013? Thank you for your help.
