Question

When I open Acrobat, a completely white popup appears and it freezes.

PCを買い替えて、Windows 11になりました。新しいPCでAcrobat Proを起動すると、白いポップアップ画面が表示され、その画面が閉じられずAcrobat本体を操作できません。

Creative Cloud Proのプランに入っています。
Creative Cloud Desktopではプラン情報は表示されています。Web版のAdobeアカウントでも契約プランは確認できます。

パソコン操作は苦手なので、お恥ずかしながらchatGPTに相談しました。

以下は実施済みです。

・Acrobat Proのアンインストールと再インストール
・Creative Cloudからのログアウト、再ログイン
・OOBEフォルダのリセット
・AcrobatのDCフォルダのリセット
・Shiftキーを押しながらのAcrobat起動

こちらで紹介されていた対処法
・Acrobat Cleaner Toolによるクリーンアップ

それでも、Acrobat Pro起動時の白いポップアップが消えず、操作不能です。
ライセンス認証または起動時Welcome画面の読み込み不良を疑っています。

対処法は何かないでしょうか。仕事上PDFが使えないのは非常に困ります。

    Hi Exuberant_Journey8098,

     

    We’re sorry to hear that the suggestion didn’t help.

    Could you please confirm if the issue occurs only with Adobe Acrobat, while other applications on the Creative Cloud desktop are functioning properly? If that’s the case, we recommend you uninstall Acrobat using the Creative Cloud desktop application. Then, please reinstall the application by following these steps:

    If reinstalling the application does not resolve the issue, we can arrange a callback for you. Please share your contact details and preferred time frame in a private message. You can click on my profile and select "Send Message" to initiate that.

     

    Let us know if you need any help.

     

    Thanks,

    Meenakshi

    Hi Exuberant_Journey8098,

     

    Thank you for reaching out, and sorry for the trouble caused.

     

    This is most commonly caused by a sign-in/activation UI issue, a GPU rendering conflict, or a corrupted configuration component that wasn’t fully cleared during reset. Please try the troubleshooting steps suggested below:

    1. Try launching Acrobat with GPU disabled

    • Right-click the Acrobat shortcut

    • Select Properties

    • In the Target field, add /n /safemode

    • Launch Acrobat

    1. Clear Adobe Identity / Sign-in cache using the steps suggested below:

    • Close all Adobe apps

    • Navigate to: C:\Users\<YourUser>\AppData\Local\Adobe\

    • Rename/delete these folders:

      1. Identity
      2. Web Services
    • Also check: C:\Users\<YourUser>\AppData\Roaming\Adobe\

    • Delete these folders:

    1. AcrobatSLStore (if present)
    2. Restart PC
    • Open Creative Cloud Desktop → sign in → then launch Acrobat.

    1. Run Acrobat as an administrator

    • Right-click Acrobat

    • Run as administrator

     

    Let us know if that helps.

     

    Thanks,

    Meenakshi

    Hi Meenakshi,

    Thank you very much for your detailed reply.

    I tried all the suggested steps, but unfortunately the issue still persists.

    Here is what I tried after your reply:

    • Launched Acrobat with /n /safemode

    • Ran Acrobat as administrator

    • Checked C:\Users\<YourUser>\AppData\Local\Adobe\, but I could not find the Identity or Web Services folders

    • Checked C:\Users\<YourUser>\AppData\Roaming\Adobe\, but I could not find AcrobatSLStore

    • Reset the AcroCef and webview2 folders

    • Confirmed that Microsoft Edge WebView2 Runtime is already installed

    • Tried launching Acrobat completely offline, but the same white pop-up still appeared

    • Created a new Windows user account and tried launching Acrobat there, but the same issue occurred

    • Tried changing the registry values bEnableAV2=0 and bShownViewerOnboarding=1, but there was no improvement

    The white pop-up still appears when I launch Acrobat Pro, and the background becomes dark. I cannot close the pop-up or operate Acrobat at all.

    Since the same issue occurs even with a new Windows user account and even when offline, it does not seem to be only a user profile or network issue.

    Do you have any other suggestions?
    If not, I will contact Adobe official support directly.

    Thank you again for your help.
