Purchased Tab for Excel, due to this facing problem with Word and Power Point

Question

Hi all,

I Recently purchased Tab for excel, it is working fine with excel. But, this application is not allowing to open two instances of word and power point. If I will open multiple word file, only recently open file will be visible, same is in case of PPT. Really very bad experience, can someone, please help in this.

Extend office team, please help in this, to use the word and powerpoint properly, I am compelled to uninstall "Tab for Excel". Means, my purchase of this was complete wastage of money. Looking forward for prompt support, please help.
