Can not preview with Adobe Acrobat Reader

[Glority_Developer]

Hi,

We find two issues related with Adobe Acrobat Reader:

• Win10 32bit: can not preview with Adobe Acrobat Reader DC(latest version) or Adobe reader XI installed.
• Win7 32bit: can preview but exit slowly with Adobe Acrobat Reader DC(latest version) installed, normal with Adobe reader XI installed.

The reason for can not preview: method DoPreview() return E_FAIL.The reason for exit slowly: method release() is slowly when first time close the preview.

Please take a look at the demo in attachment, we are  looking forward to your reply, thank you very much.
